Hi, Tom!

It's great to hear you're working on this project!  It's hard to say what's
wrong with your setup, but here're some things I noteced.

First, KERNVIRTADDR appears to be incorrect in your setup as you're trying to map
the kernel very low (0x01008000).  In this case very low amount of virtual
address space will be left for user-level applications.  Try to map it to
some address above 0xc0000000, e.g. to 0xc1008000.

I also do not quite understand why you're using address 0xa0100000 for the
first helper page mapping?  What is the layout of memory on your board?
Is anything useable is mapped here?

Good luck!
